The unit continuously auto cycles through each of the active channel screens for constant, up-to-date readings.

The RD-64X provides Alarm/Fault status indication on front panel LEDs. Alarm relay outputs can be configured as Latching/Non-latching, Energized/De-energized and Silenceable/Non-silenceable on each unit using one Detcon RL-4 module.

Among the system’s unique features is a wireless option that can be used with Detcon’s RXT-320 SmartWireless® transceivers. Enclosure options include NEMA 4X (Model RD-64X-N4X) powered by either 110/220VAC or 24 VDC using an internal power supply and NEMA 7 (Model RD-64X-N7) powered by 11.5-30VDC using an external voltage source. Model RD-64X-N4X includes an external Reset/Acknowledge switch as standard (optional on Model RD-64X-N7).

The Detcon Model 1000 Series H2S and CO2 gas analyzers are designed to provide accurate and continuous measurement of target gas concentrations in natural gas treating plants, gas production wells and at custody transfer points along gas transmission pipelines. The application flexibility of this family of analyzer products is based on utilization of proven sensor technologies and the ability to customize according to the application.

In the Model 1000, Detcon’s long history of gas monitoring sensor research and manufacturing is combined with a field tested and proven pedigree in sampling system design and operation. The result is a simple and economical yet powerful analytical tool offering capabilities equivalent to analyzer technologies costing much more. Long sensor life, easy operator interface and embedded intuitive maintenance scripts help to maintain high quality analysis of H2S and CO2 content in natural gas processes.
